i was wondering if somebody could give their opinion on what's wrong with my car. my CEL turned on and the codes said that i had a misfire on cylinder 1. my cousin suggested to test the coil pack so we took it out and it looked fine. the spark plugs looked fine also. i then switched the coil pack from cylinder 3 to cylinder 1 and vis versa and the light didnt turn on for about a month. it recently turned on again and now it says that both cylinders 1 and 3 have a misfire. does anybody know what it could be.
